Do I need a new feedneck?

I got a new Ion XE a few days ago and my dad bought a pack of 3 used guns off of eBay. This package also included two hoppers, and two HPA tanks. One of the hoppers was a Halo TSA and the other was a Ricochet AK hopper. Both of them won't fit in my Ion's feedneck because it gets extremely tight as I push it in. Am I going to need a new feedneck and if so, which one would work well?
